Law Enforcement Training Bulletin — September 2026

In three landmark decisions issued in 2025 and 2026, the U.S. Supreme Court reinforced a single core principle for law enforcement: courts must evaluate police conduct by looking at the totality of the circumstances — not by isolating individual moments or facts.

Barnes v. Felix (2025) — Use of Force: The Court unanimously rejected the Fifth Circuit's "moment-of-threat" rule, holding that all relevant events leading up to the application of force must be considered, not just the final seconds before a shot is fired.

Zorn v. Linton (2026) — Qualified Immunity: The Court upheld qualified immunity for an officer who used a wristlock on a non-compliant protester, emphasizing that qualified immunity requires prior precedent with a high degree of specificity before an officer can be held liable.

District of Columbia v. R.W. (2026) — Reasonable Suspicion: The Court reversed a suppression ruling, finding that a late-night suspicious vehicle call combined with the unprovoked flight of passengers gave the officer reasonable suspicion — criticizing lower courts for "excising" key facts from their analysis rather than considering the whole picture.

Together, the decisions underscore the importance of officers documenting and articulating the full context of every encounter, from initial contact through the end of the interaction.
